The Nanoscale Photonics and spectroscopy laboratory (NPs-Lab) at Xiamen University is a research group led by Prof. Jun Yi. We investigate nanoscale optical phenomena with an emphasis on the underlying physics of light–matter interactions under extreme spatial and temporal confinement. Leveraging these insights, we advance high‑sensitivity, high‑resolution spectroscopies and bespoke instrumentation to enable in situ, time‑resolved, multi‑scale and multi‑dimensional characterization of complex interfacial processes.
